Jamie Roberts reckons Cardiff Blues are in perfect shape to topple London Wasps and claim European glory.

The Wales centre touched down in the Blues' seven-try 55-20 romp at Newcastle to set up a semi-final with Wasps.

And Roberts says Blues are peaking at just the right time ahead of the May 1 clash at Adams Park. He said: "The semifinals are never easy but we've shown we are capable of playing well away this season."

Cardiff face Scarlets in the Magners League tomorrow and Roberts added: "If we win it will guarantee us Heineken Cup rugby next season."
